Khashoggi, a critic of de facto Saudi ruler Crown Prince Mohammed bin Salman, was killed in Saudi Arabia's Istanbul consulate on Oct. 2 in a hit which Erdogan says was ordered at the "highest levels" of the Saudi government. Six weeks after Khashoggi's death, Turkey is trying to keep up pressure on Prince Mohammed and has released a stream of evidence that undermined Riyadh's early denials of involvement. Prine Mohammed won support on Tuesday from U.S. National Security Adviser John Bolton, who said he did not think recordings of the killing shared by Turkey implicated the young crown prince.
